Can someone explain how to solve x 2(x+10)=20

trapecia [35]

So first you are going to want simplify the left side of the “=“ sign by multiplying the number outside the parenthesis, 2, by the numbers inside the parenthesis, (x+10). So, 2*x= 2x and 2*10=20. Bringing you to 2x+20=20, from here you want to isolate the variable, 2x, so you have to subtract 20 from both sides to do so. This brings you to 2x=0, when a variable is equal to zero, in specific problems, like this one, it is right, but always make sure to check your answer because in some problems when the variable is equal to 0 the answer is sometimes No Solution, so be careful. The way you want to be sure that x=0 in this equation is the plug it into the original equation, 2(x+10)=20, so it would be, 2(0+10)=20 and this goes to 2(10)=20, multiply the outside number to the inside which gives you 20 so then 20=20. It matches so it’s correct, THE ANSWER IS x=0, sorry if I made it complicated.

587×6543÷285{32+65}= ? HELP

Ludmilka [50]

Answer:

1307199.57

Step-by-step explanation:

Follow BEDMAS (brackets first, then exponents, then multiplication and division, then addition and subtraction)

587x6543÷285(32+65)

32+65=97

587 x 6543 ÷ 285 x 97

= 3840741 ÷ 285 x 97

= 13476.2842 x 97

= 1307199.57

The area of a rectangular wall of a barn is 280280 square feet. its length is 88 feet longer than twice its width. find the leng

k0ka [10]

Hello,

Making an equation would be a good method to solve this problem.

The area of a rectangle is equal to $l * w$ , where l is the length and w is the width of the rectangle.

If the area of the wall is 280280, we know $l * w$ = 280280
We also know that the length is 88 feet longer than twice the width. Twice the width is equal to $2w$ , and the length is 88 feet longer than that, so $l = 2w + 88$ .

So, we have a system of equations:
$l * w = 280280
$
$l = 2w + 88$

Using the first equation, we can find the value of l and we get $l = \frac{280280}{w}$

We then plug in this value of l into the second equation, and we have:
$\frac{280280}{w} = 2w + 88$

Now, we can multiply by w on both sides, and subtract 280280 on both sides, and use the quadratic formula to get w ≈ 353, -397

The width of a wall cannot be negative, so the answer is 353 feet.

To find l, and make sure of our answers, we should check it with the original problem to make sure it checks out.

Doing this, we get:
$353 * l = 280280$
Divide by 353 on both sides to get:
$l = 794$

Now, we should check it with the equation $l = 2w + 88$
794 = 2(353) + 88
794 = 794, checks out.

So, the width of the wall of the barn is 353 feet, and the length of the wall of the barn is 794 feet.

Hope this helps! Feel free to contact me with any questions you may have.
